摘　　要：专门讨论了对高维信息的线性降维处理，由于是线性的，它的处理相对简单，由于将原始信息降维了，后续提取真正需要的信息处理又将变得比较容易了。这样的降维处理可以在电子战领域内得到广泛的应用，文章就阵列测向和信号识别两个方面，扼要地介绍了应用这个基本方法的思路。通过仿真分析，给出了应用所能产生的效应，提出了随意阵高精度测向的基本方法和多特征压缩识别的基本方法。The dimension shrinking of high dimension data is discussed in this paper. As it is a linear processing, it is simple. As the dimension is decreased, the following processing for getting the information within the data becomes easier. Such processing can be widely used in EW field. Application examples of DF and identification are presented to introduce the main idea in specified task. The effect of the method is shown through simulation, as a result, high accuracy DF with arbitrary array and new identification with multiple characteristic are shown as new methods.
